Set the data recording interval for the data logger
The data recording interval for the data logger defines the intervals at which
the integrated data logger records are to be recorded. If you select a shorter
interval, then the recording time is also short and the record will be a detailed
one. If the intervals are longer, then the possible recording time is also longer
and the resolution of the weather data is lesser.
- Select the "SYSTEM" menu and then the "INTERVALL" option (via BEEP, and
DST); the display is:
INTERVALL
+ 05 -
- Touch the "+" or "-" fields to set the interval time (OFF (data logger is off), 5
minutes to 60 minutes). You will find in the following section a few examples for
the relationship between interval time and recording time

"ALTITUDE", Adjust the location height above sea level
The standard altitude is used for calculating the relative air pressure at sea level
with reference to the absolute air pressure at the location. This relative value is
important as a reference for correctly interpreting the weather reports that refer to
the relative air pressure.
- Select the "SYSTEM" menu and then the "ALTITUDE" option (via BEEP, DST
and INTERVALL), the display is:
You can determine your height above sea level in different ways:
- You can find the height in a topographic map or ask your local land registry
office.
- If you have a GPS navigation system in the car or a mobile device you can take
over the position details and you will thus have the exact location.
- You can also find out the height above sea level from the Internet.
